Magnetic iron oxide nanocomposites: types and biomedical applications

Magnetic nanocomposites are generally multiphase systems, mostly inorganic or sometimes organic–inorganic composites, which could combine the features of constituent blended materials. In literature, multiple reports are available about these functional or complex materials in many applications, especially in the biomedical field. In biological systems, these multifunctional nanocomposites are mostly used in drug delivery, diagnosis of disease, and monitoring of therapeutic response. These magnetic nanocomposites would play a significant role in the future era of personalized medicine, and therefore it is a hot research topic nowadays. Moreover, the catalyst recovery is quite simple in the case of magnetic iron oxides nanoparticles (MIONPs) nanocomposites due to their paramagnetic nature, which further adds to their remarkable properties. Owing to their unique characteristics, MIO nanocomposites can be employed in various biomedical applications. Considering the established literature review and their significant commercial aptitudes, MIO nanocomposites can be considered as a broad class of modern materials for artificial intelligence and other discovering technologies in the field of medicine as well as other industries.
